EEE MCQ: Semiconductor Theory

Semiconductor any of various solid crystalline substances, such as germanium or silicon, having electrical conductivity greater than insulators but less than good conductors. In electronics these are generally doped to from either N-type or P-type material. These materials are the foundational material for diodes and transistors, which is used on electronics circuit. Silicon is the most common material used to build semiconductor devices.
